PORTION CONTROL? I think it is important, but less so if we focus on eating food that is not calorie dense. If you eat a high-fat, high sugar diet, portion control is critical. If you’re eating lots of, say, brocolli and beets, with a modicum of low-fat meat/fish, you will get full without so many calories.
“The push to re-evaluate serving size comes as the F.D.A. is considering ways to better convey nutrition facts to hurried consumers”
You don’t have to worry about these calculations if you are eating “real food.” Potato chips do not count as such 🙂
